Picture from display showin one set of black lines on image at FHD resolution.

On gentoo, nothing changed but kernel. After kernel build of kernel version
some 3 months ago I notice in HD4000 graphics of ivy bridge strange phenomenon.
Black lines every few lines. Looks like some stride value incorrect computed. 

Have attach image with picture showing black lines. FWIW if screenshot taken
lines do not appear. I tested with display with external and internal displays
and only appears with linux. Running macos problem not appear.
